利用高产、抗寒力强的亲本进行有性杂交，通过抗寒前哨苗圃抗寒性的选择和初级系比、高级系比，以及生产性试验系统资料的鉴定，云研７７—２和云研７７—４在生长、产量、抗性等方面优于ＧＴ１，特别是云研７７—４抗寒能力强。推荐在云南省西部植胶区的重寒区中规模种植；东部植胶区中寒区试种。

Using the high-yield, cold-resistant parents of sexual crossbreed, through the selection of cold resistance in cold outpost nursery and the primary line ratio, high line ratio, and identification of productive test system data, Yunyan 77-2 and cloud research 77-4 is superior to GT1 in terms of growth, yield, resistance, and the like, and especially Yunyan 77-4 has strong cold-resistance ability. It is recommended that large-scale planting is carried out in the heavy cold area in the plastic planting area in western Yunnan Province;
